Greetings @elvenprincess2 I can imagine this is frustrating for you and members of your FS however I don't believe there is a way to restrict other players outside of the FS from contributing to your AWs. Have you noticed if it's the same Neighbours that continue to Contribute? Is it a particular FS that keeps doing this?
They may be under the impression they are helping and most certainly wont be aware that you would prefer it only from FS Members.
I would maybe contact the Players concerned and advise them (Kindly) that whilst you appreciate the help, you're FS has a strict policy concerning AW Research.
If you have space, and they are without an FS, even go as far to invite them if you so wish :)
Let me know how you get on!

Kind Regards

Herodite.
